    Summary:

    Details: A vulnerability was found in the PCS project. This issue occurs due to incorrect permissions on a Unix socket used for internal communication between PCS daemons.

With the "hacluster" token, this flaw allows an attacker to have complete control over the cluster managed by PCS.
